Questions
Is there a KiCad symbol and footprint for the AO3402?
Yes. the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AO3402?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the AO3402 datasheet?
SEP publishes it: the Datasheet link on this page opens it.
Where can I order the AO3402?
JLCPCB lists it as part C50176481, with 2,777 in stock; the sellers' links on this page open their listings.
What can replace the AO3402?
Parts like it in the library: the SI2318 by GOODWORK, the 6P03 by GOODWORK, the AP3401BI by A Power microelectronics and the BL3407 by Galaxy Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
